grep

 
Find patterns in files using regular expressions. More information: https://www.gnu.org/software/grep/manual/grep.html.
 
  • Search for a pattern within a file:
     
    grep "{{search_pattern}}" {{path/to/file}}
     
  • Search for an exact string (disables regular expressions):
     
    grep --fixed-strings "{{exact_string}}" {{path/to/file}}
     
  • Search for a pattern in all files recursively in a directory, showing line numbers of matches, ignoring binary files:
     
    grep --recursive --line-number --binary-files={{without-match}} "{{search_pattern}}" {{path/to/directory}}
     
  • Use extended regular expressions (supports ?, +, {}, () and |), in case-insensitive mode:
     
    grep --extended-regexp --ignore-case "{{search_pattern}}" {{path/to/file}}
     
  • Print 3 lines of context around, before, or after each match:
     
    grep --{{context|before-context|after-context}}={{3}} "{{search_pattern}}" {{path/to/file}}
     
  • Print file name and line number for each match with color output:
     
    grep --with-filename --line-number --color=always "{{search_pattern}}" {{path/to/file}}
     
  • Search for lines matching a pattern, printing only the matched text:
     
    grep --only-matching "{{search_pattern}}" {{path/to/file}}
     
  • Search stdin for lines that do not match a pattern:
     
    cat {{path/to/file}} | grep --invert-match "{{search_pattern}}"
